Extend the order-independent annotation parsing logic to include the following forms: @foo // bare annotation (already supported) @foo(0x70) // decimal literal @foo(HI) // identifier @foo("hello there") // quoted string This is obviously still pretty far from annotations in other languages, which usually support arbitrary expressions and multiple parameters, but I think it's sufficient to cover a pretty good variety of usages. The existing class-field annotations @if and @ifnot are reimplemented in the new style, meaning they could now appear in any order relative to other annotations on the same field (and can be repeated, though I doubt it would be of much use to anybody).

This patch implements the declaration of private accessors. When iterating over the class properties, we track private accessors associated with the same name in a ZoneHashMap. Once we get to all the necessary components for a private name (we know statically whether we should expect only a setter, only a getter, or both), we emit a call to a runtime function `CreatePrivateAccessors` that creates an AccessorPair, and store the components in it. The AccessorPair is then associated with the private name variable and stored in the context for later retrieval when the private accessors are accessed.

Fixes bytecode mismatch between lazy and non-lazy where "this" was marked as maybe assigned in constructors that called the super constructor. Since this will return the hole in cases where it was not yet initialized by super (and the hole is explicitly handled by JSContextSpecialization::ReduceJSLoadContext), it's safe to treat it as a constant in all cases. In the case of lazy compilation case, "this" is never added to the ScopeInfo so is never seen as mutable.

Before dd6f4d4f, this function was reading a single u8 and verifying that it was 0x00. The referenced commit dropped this check as part of implementing decoding for table.get, but neglected to change the read type to u32v, which is the specified type of this immediate. Fix that.

Jakob Gruber authored
The deoptimizer calculates frame layout based on the translation's `height` field, together with additional data (e.g.: are we looking at the topmost frame? what kind of deopt are we in?). The result is the final deoptimized frame size in bytes, together with a bunch of intermediate results such as the variable frame size (= without the fixed-size portion). In order to consider the deoptimized frame size in optimized stack checks, we will need to calculate the frame layout during compilation in addition to what we currently do during deoptimization. This CL moves in that direction by extracting relevant parts of frame layout calculation into classes that can be reused by both compiler and deoptimizer. These helpers will support both precise and conservative modes; the deoptimizer will use the precise mode (since it has full information), while the instruction selector will use the conservative mode.

Chromium has checks which don't like static initializers in binaries, which fires on effect_control_linearizer.cc. We can remove these by making kMinusZeroBits (and family) constexpr, but to do this we have to avoid bit_cast. Instead, set the correct bit pattern manually (thankfully IEEE 754 0.0 is just zero bits, and -0.0 is 0.0 with a set sign bit).

This is a very small change which must go in before https://chromium-review.googlesource.com/c/chromium/src/+/1731108 is able to land. Certain WPT tests for synthetic modules were spawning DCHECK crashes by JSObject::SetNormalizedProperty. Export names were previously failing: DCHECK(name->IsUniqueName()); This small change corrects the issue and allows Module::GetModuleNamespace to run correctly. This change aligns synthetic module behavior for export string storage with JS modules, as well as the spec. chromium: 967018 Change-Id: I151e7150290bd72d4e4753c8c5be243eafae915f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1761583Reviewed-by: Georg Neis <neis@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Commit-Queue: Georg Neis <neis@chromium.org> Cr-Commit-Position: refs/heads/master@{#63264}
